<h2 class="description">Description</h2>
<p>
TPlotGraph represents a graph of the plotter. It has a name, a color, a hint (tooltip text, which is derived from its name), a pointer to its function and it can be visible or hidden. It also has a value buffer, which caches function values on a per pixel basis (depending on the plotter precission property) for the current viewing area.</p>
